Those disturbed by the needless immiseration of innocent children should beware. “Saving Africa’s Witch Children” follows Gary Foxcroft, founder of the charity Stepping Stones Nigeria, as he travels the rural state of Akwa Ibom, rescuing children abused during horrific “exorcisms” — splashed with acid, buried alive, dipped in fire — or abandoned roadside, cast out of their villages because some itinerant preacher called them possessed.

…

some have read her book “Unveiling the Mysteries of Witchcraft,” where she confidently writes that “if a child under the age of 2 screams in the night, cries and is always feverish with deteriorating health, he or she is a servant of Satan.”

…

in her sermons, Ms. Ukpabio is emphatic that children can be possessed, and that with her God-given “powers of discernment,” she can spot such a child. Belief in possession is especially common among Pentecostals in Nigeria, where it reinforces native traditions that spirits are real and intervene in human affairs.

…

Since “Saving Africa’s Witch Children” was first shown in Britain, in 2008, Mr. Itauma’s home state has adopted a law against accusing children of witchcraft. But Ms. Ukpabio went on the offensive by suing the state government, Mr. Foxcroft, Mr. Itauma and Leo Igwe, a Nigerian antisuperstition activist.

In the lawsuit, Ms. Ukpabio alleges that the state law infringes on her freedom of religion. She seeks 2 billion naira (about $13 million) in damages, as well as “an order of perpetual injunction restraining the respondents” from interfering with or otherwise denouncing her church’s “right to practice their religion and the Christian religious belief in the existence of God, Jesus Christ, Satan, sin, witchcraft, heaven and hellfire.”

In other words, in the name of religious freedom, Ms. Ukpabio seeks a gag order on anyone who disagrees with her.

This is Christianity at its very worst. The strategies employed by Ms. Ukpabio mirror those we see in the US from conservative Christians – claim persecution and vigorously defend their “right” to persecute and vilify others – often with violent results.

In general one wants to say people have a right to preach and spread ignorance. One’s will to defend this right begins to erode when that ignorance clearly leads to violence. What is absolutely clear is that we do have a right to criticize that ignorance and do our best to counter it. That means everything from explaining the difference between autism and witchcraft to tackling a belief system that was founded on bronze age fears of the unknown – and fears of competing belief systems.
